Play to set a score, then submit it to the board.
How to play
- Notes fall down four lanes toward the judgement line at the bottom.
- Press the matching lane key (D, F, J, K) — or tap the lane on touch — exactly as the note crosses the line.
- A Perfect hit scores more than a Good hit; missing a note costs a life and resets your combo.
- Clear all 5 stages before you run out of lives to win the run.
Strategy & tips
- Watch the judgement line, not the falling note — let the note come to you instead of chasing it up the lane.
- The Perfect window is tight; if you are consistently early or late, nudge your timing by half a beat.
- Combo drives your score multiplier, so protecting an unbroken streak beats chasing one risky Perfect.
- Later stages layer more notes per beat — lock onto the rhythm rather than reacting note-by-note.
- Practice mode replays a stage without spending a daily attempt — use it to learn a hard section first.

A miss breaks your combo and costs a life. Run out of lives before clearing the stage and the run ends.
